Dental billing

Please use the information on this page to help ensure your dental claims are processed quickly and correctly. Note: Please do not submit attachments (e.g., X-rays, periodontal chartings) with your pretreatment estimate or initial claims submission. If additional information is needed, we will send you a request.

Submit diagnosis codes on dental claims

On January 1, 2021, we will require diagnosis codes on certain dental claims to support expanded dental care benefits for patients with such conditions as heart disease, diabetes or pregnancy. Diagnostic codes will identify why a procedure was performed and the associated disease, illness symptom or disorder.

We encourage you to begin including diagnosis codes when submitting dental claims to us as soon as possible. To submit your dental claims using the online claims submission tool on the Availity Portal: Go to - Claims & Payment>Dental Claim. You can submit up to four diagnosis codes in the Record of Services Provided section.

The Avality Portal also includes training on how to submit a dental claim: Go to – Help & Training>Find Help>Claim Submission>Dental Claims>Submitting Dental Claims.

Dental benefit predetermination

Submit a dental benefit predetermination (pretreatment estimate) electronically for a courtesy review. Our response will be sent to you via letter. Note: Predeterminations cannot be viewed on the Availity Portal.

Benefits will be predetermined under the assumption that Regence is the primary insurer. If the patient is insured under more than one policy, actual benefits payable may be adjusted due to coordination of benefits (COB) or maintenance (non-duplication) of benefits (MOB).

Predeterminations are provided as a courtesy and are not a guarantee of payment. All services are subject to the benefits, eligibility and maximum allowable amounts in effect on the actual date of service. Estimated payment may be reduced due to prior payments for treatment. Actual benefits payable will depend upon the following:

  • Benefits available
  • Member contract limitations
  • Provider participating status
  • Patient and provider eligibility
  • Benefit maximums in effect when the services are completed

Orthodontia billing guidelines

Orthodontia is a separate benefit from other dental services. Check the member's benefits to determine whether it is a covered service. Orthodontia for periodontal reasons is covered only if the patient has orthodontic benefits. Please access the Availity Provider Portal prior to treatment to determine if your patient has orthodontic benefits.

You can bill the total orthodontia treatment cost up-front without the breakdown of payments, except when treatment was received prior to eligibility or probation:

Notes related to the above exception:

  • Submit claims electronically using valid orthodontic codes along with the following information in the Claims Notes or Remarks section:

    • Banding date
    • Total treatment charge
    • Monthly payment amount
    • Estimated length of treatment
    • Initial banding fee or down payment
    • Orthodontic treatment that started before the member's effective with Asuris will be reimbursed in proportion to the time remaining in treatment.

Example: If a member's effective date with Asuris is in the sixth month of a 24-month course of treatment, payment will be prorated to the 18 months in which they become eligible. This payment, when combined with any payment made by a previous insurance carrier, cannot exceed the total billed amount.

Note: Orthodontia benefits for some groups are structured to pay for periodic treatment visits, as indicated in the member's benefits. If you are not able to submit electronic claims for periodic treatments and the payment received for your initial claim is not equal to the amount of the member's available orthodontia benefit, please submit monthly or quarterly visit claims until benefits are exhausted or the patient completes treatment via fax to 1 (888) 606-6582. The last claim for treatment must indicate the date that the patient was de-banded.

Necessary dental care

The following criteria are used to determine if a service is necessary:

  • It is consistent with widely accepted standards of practice.
  • It is not primarily for the convenience of the member, the dental provider or any other person.
  • It could not have been omitted without adversely affecting the member's condition or quality of care.
  • It is the least costly, appropriate treatment and location that can be used safely to treat the member's condition.
  • It is the appropriate type, level, amount and frequency of care necessary to treat a dental condition or injury that is harmful to the health of a member.

Accidental injury definition

A dental accidental injury is defined as involving damage to the natural, sound and healthy tooth or tooth structure.

Medical claims billed by dental offices

Dental offices performing procedures not on or contiguous to a tooth must report the service on a medical claim form, with Current Procedure Terminology (CPT®) codes. These codes must be reported with the appropriate ICD-10 diagnosis codes.

ICD-10 coding resources
These resources may be helpful when submitting medical claims which require ICD-10 coding:
